CHARLES NAEGELEN AND AUGUST Gr. KLAWITTER, OF CINCINNATI, OHIO,ASSIG'NORS TO THE CINCINNATI BUTCHERS SUPPLY CO., OF CINCINNATI, OHIO, ACORPORA- LARD-STRAINER.

To all whom 2f may concern:

Be it known that we, CHARLES NAEGELEN and AUGUST G. KLawrr'rER, bothcitizens of the United States, and residing in Cincinnati, Hamiltoncounty, State of Ohio, have invented certain new and useful Improvementsin Lard-Strainers; and we do declare the following to be a clear, full,and exact description of the invention, attention being called to thedrawing which accompanies this application and forms a part thereof.

Lard leaves the kettles and containers in which it has been rendered inconsistency of a limpid fluid. l/Vhile still in this condition it iscaused to flow through straining devices to free it of matter notreducible to lard like for instance remnants of skin and meat, fibrousmatter and cracklings.

Our invention relates to such straining devices and consists of a deviceconstructed with a view to make it adaptable for the particular purposeof rendering lard.

In the following specification and particularly pointed out in theclaims at the end thereof, will be found a full description of ourinvention, together with its operation, parts and construction, whichlatter is also illustrated in the accompanying drawing, in which Figure1, is a top-view of our lard straining device. Fig. 2, is a verticalcross-section of the same. Fig. 3, shows in side-elevation, partly insection, one of the separable parts detached.

Our strainer consists of a number of individual strainer-elements, eachcomprising a multi-perforated diaphragm A, through which the lard isadapted to pass and a frame a whichv supports this diaphragm. Theseelements are arranged so that a number of them, with perforations ofgraduated sizes, may be assembled in a manner causing the lard to flowthrough them successively. The element with the largest perforations isencountered first by the lard which passes successively through theother elements with the smaller perforations, the element through whichthe lard passes last having the smallest perforations. The frames whichsupport the diaphragms are annular and each consists of twosupplementary members 6 and 7, of congruent shape, 1which hold betweenthem the edges of the diaphragms. These frame-members are held to eachother by clamping-screws 8.

Specification of Letters Patent.

Application led April 22, 1912.

serial No. 692,447.

The diaphragms are by preference in form of screens made of wire clothand to hold their edges securely the opposite surface of theframe-members between which these edges are held are offset as shown at9, the edge of the cloth being clamped around these o-sets. Threeelements are shown in the drawing and they are arranged in form of astack. They are held alined, one superposed upon the other, by havingthe opposite surfaces of the frames where they rest upon each otherolf-set as shown at 10. The strainer-elements rest in a settling chamber11, being introduced through the open top thereof. The bottom of thischamber is provided with an annular ridge 12, upon which the frame ofthe lower-most strainerelement rests, said ridge being spaced from thechamber-wall to which it is concentric and its top being off-set in amanner similar to the opposite surfaces between the frames which aretted to said top. The diameter of this chamber is of a size to permitthe lard which discharges from a conduit 13, to flow into the spaceoutside of the strainers, in which space it rises until it overflowstherefrom into the upper-most strainer no pressure being applied. Thelard passes through all the elements below and discharges through anoutlet 14 below the lower-most strainer. Foreign matter which by reasonof its size and weight does not flow with the lard is thus held back inthe settling chamber, so that the strainers are not encumbered thereby..This matter may be letout from time to time through a valvecontrolleddrain-pipe 15, the inow through conduit 13 being cut o for the timebeing. The frame of each strainer-element is provided with handles 16,to permit them to be manipulated, lifted out for cleaning and replacedagain.

The elements may be readily placed and interchanged by reason of theirinter-fitting frames.

Having described our invention, we claim as new:

1. In a lard strainer, the combination of a cylindrical settlingchamber, a series of superposed strainer-elements stacked therein andcomprising annular frames and diaphragms with openings of graduatedsizes,

4the element with the largest openings being uppermost but below the topof the settling chamber, the frames of the elements being smaller indiameter than the inside of the chamber and closely itted to eaeh otherto produce an annular space around the elements, but closed againstthem, a supply conduit to admit lard to this space in which it rises andHows into the upper -most strainer-element, an outlet Jfor the strainedlard below the lower-most element and an independent. outlet from thesettling-(maur ber.

2. In a lard strainer, the combination of a cylindrical settling-Chamberhaving an open top and an annular ridge on its bottom spaced from theside of the Chamber, an outlet in said bottom and within this ridge, astack of strainer-elements smaller in diam eter than the chamber' andwith openings of graduated sizes restino' upon this ridge7 and a supplyconduit to admit lard to the space between the outside of the strainerelements and the chamber in which it rises and flows over into theupper-most strainer-element and through all the elements to the outletbelow them.

A lard strainer element consisting of two annular, superposedcomplementary frame-members provided with inter-fitting off-sets betweentheir Contiguous sides, a perforated diaphragm supported transverselybetween these frame-members and extending with its edge between them andover their inter-fitting oli-sets and screws whereby the twoframe-members are permanently secured to eaeh other with the edge of thediaphragm clamped between their olfsets, to form the element complete.

In testimony whereof, we hereunto ailix our signatures in the presenceof two witnesses.
